oh, what is DUE variable?

I tried the program, and it works for me. I assume that your .03 entry is for the interest . Try entering 0 for [DUE].

When you get Nonexistent, go to PRGM mode to check which command is causing the error. It sounds like the problem might be an uninitialized variable.

You should also see a program named TVM in the program list. It is called by MORT, and if it is not present you will get the nonexistent error.

Received calculator yesterday, May 15. It took 27 days to get to Colorado from Switzerland.

Perhaps it shipped on a boat ?
